Portrait of Charles Doolittle Walcott Charles Doolittle Walcott,  Cambrian Geology and Paleontology (1914)

“ The function of the proboscis and its terminal spines is unknown; it appears to be adapted to the gathering of food and conveying it to a mouth beneath the head, but it was probably used by the male to seize the female.
If we consider the appendage-bearing somites as the thorax, the abdomen is confined to the one elongated expanded somite I have referred to as the telson. This does not show evidence of segmentation unless there is a post-anal plate, which is very doubtful. None of the specimens of the male show any traces of caudal appendages.

Herbert Newton Casson,  The History of the Telephone

“ These telephone girls are the human part of a great communication machine. They are weaving a web of talk that changes into a new pattern every minute. How many possible combinations there are with the five million telephones of the Bell System, or what unthinkable mileage of conversation, no one has ever dared to guess. But whoever has once seen the long line of white arms waving back and forth in front of the switchboard lights must feel that he has looked upon the very pulse of the city's life. ”

Portrait of Burton Egbert Stevenson Burton Egbert Stevenson,  The Young Train Dispatcher

“ Indeed, most of them can and do work the key with one hand while they eat their lunch with the other; and the call or signal for his office will instantly awaken him from a sleep which a cannon-shot would not disturb. Telegraphy, in a word, develops a sort of sixth sense, and the experienced operator receives or sends a message as readily as he talks or reads or writes. It is second nature. ”
